Because they want to race. It's not because they're jealous, or gawk, or wish they had an M3. It's because they know you'll be sucking on their exhaust in a straight line. What world do you people live in? Why would anyone who owns a 70k car be jealous? He'd probably be able to buy an M3 if he wanted. Someone with that kind of income to own an "high performance" car in todays economy is doing really well. This is exactly why BMW drivers are hated. Because they're so cocky, and think they're higher then everyone else.
